Projected/Forecasted Date from values

Thanks Estevaoba

I'm now looking to plot this info into a graph.

So, i'd like to see X projected calendar date plotted to the dates listed in column F with a dotted line being present on the graph where X cut off date is column G

i've included an image to show what im wanting, the projected dates in F as the X axis and X projected (columb D) to be the Y axis then is it possible to add a dotted line where X cut off date lands similar to the below (blue dotted line)

i require to do this for Y projected too.

see attached for updated Spreadsheet.

Many thanks
